Overview
UNISONIC TECHNOLOGIES CO.
, LTD UT3223 Preliminary +3.
0V TO +5.
5V POWER SUPPLY, 250KBPS, MULTICHANNAEL RS-232 LINE DRIVERS/RECEIVERS CMOS IC  DESCRIPTION The UTC UT3223 consists of 2 drivers and 2 receivers.
It meets ElA/TIA-232 and V.
28/V.
24 specifications, it intended for notebook computer applications.
A high-efficiency, dual charge-pumps power supply and a low-dropout transmitter combine to deliver true RS-232 performance from a single +3.
0V~+5.
5V power supply.
A guaranteed data rate of 250kbps provides compatibility with popular software for communicating with PCs.
The UTC UT3223 achieves 1µA supply current in shutdown condition.
When the UT3223 doesn’t detect a valid signal level on its receiver inputs, the on-board power supply and drivers will shutdown, and when a valid level is applied to any RS-232 receiver input, then the system turns on again.
Therefore, the system saves power without changes to the existing BIOS or operating system.
The UTC UT3223 requires only 0.
1µF capacitors in 3.
3V operation, and can operate from input voltages ranging from +3.
0V ~+5.
5V.
It is ideal for 3.
3V-only systems, 5.
0V-only systems, or mixed 3.
3V and 5.
0V systems that require true RS-232 performance.
 FEATURES * Operates With 3.
